摘要：
To provide a method for producing a magnetic transfer master carrier, including: plating a patterned silicon substrate with nickel so as to form a base material on the silicon substrate; separating the base material from the silicon substrate; and etching a surface of the base material so as to obtain an oriented base material, wherein the magnetic transfer master carrier includes the oriented base material, a thin underlying layer formed on the oriented base material, and a magnetic layer formed on the thin underlying layer.
